WebConstant movement of all the biofilter media is essential for optimal nitrification, aeration and degassing. The moving bed filter is generally located after the fixed bed filter and before the degasser and oxygen enrichment, ahead of the water returning to the culture tank. Some of the CO2 in the water will be stripped, as well as any N2 gas ... WebThe porous rock beds used in common biofilters must be inspected, removed and cleaned regularly to maintain peak air flow. Clogged rocks limit air flow and increase stress on the system’s ventilation. Removal and …
